The Dolphin class is a diesel-electric submarine developed in Israel and constructed by Howaldtswerke-Deutsche Werft (HDW) in Kiel, Germany, for the Israeli Navy. The first boats of the class were based on the export-only German 209-class submarines, but modified and enlarged. The Dolphin 1 sub-class is slightly larger than the German Navy Type 212 in length and displacement. The three newer air-independent propulsion (AIP) equipped boats are similar to the Type 212 vessels in underwater endurance, but are 12 metres (39 ft) longer, nearly 500 tonnes heavier in submerged displacement and have a larger crew than either the Type 212 or the Type 214.
